c# - Libsodium-net - 无法加载 DLL 'libsodium.dll

Question

我通过 NuGet 安装了 Libsodium-net 并且能够在我的类中包含 Sodium，但是当我尝试运行它时，我得到了

Sodium.dll 中发生了“System.DllNotFoundException”类型的异常，但未在用户代码中处理

附加信息:无法加载 DLL“libsodium.dll”:找不到指定的模块。 (HRESULT 异常:0x8007007E)

我只是想运行 gitbooks 文档中的示例代码 https://bitbeans.gitbooks.io/libsodium-net/content/password_hashing/index.html

const string PASSWORD = "Correct Horse Battery Staple";
const string SALT = "qa~t](84z<1t<1oz:ik.@IRNyhG=8q(o";
const long OUTPUT_LENGTH = 512;

//this will produce a 512 byte hash
var hash = PasswordHash.ScryptHashBinary(PASSWORD, SALT,      PasswordHash.Strength.Medium, OUTPUT_LENGTH);

Answer 1

我遇到了同样的问题并使用 Jørn Wildt's answer given here 解决了它.

It turns out that ASP.NET doesn't make shadow copies of unmanaged DLLs such as libsodium.dll and libsodium-64.dll.

Sodium.dll (the managed code) tries to load the DLLs from either the same directory as the shadow copy of Sodium.dll (which is not going to work) - or some where in the PATH environment variable's directories.

My solution was to add the AppDomain \Bin directory to the path before calling any Sodium code:

string path = Environment.GetEnvironmentVariable("PATH");
string binDir = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Bin");
Environment.SetEnvironmentVariable("PATH", path + ";" + binDir);

正如鲁本对答案的评论；我在 Global.asax 的 Application_Start 方法中添加了上述代码。
